Easy Solution Verified by Toppr … WebFeb 23, 2024 · In C4 plants, photosynthetic tissues differ structurally and functionally from those in C3 plants. For example, bundle sheath cells in C4 plants are effectively shielded from the atmosphere by a ring of mesophyll cells (Fig. 5.20). This arrangement allows the mesophyll cells to regulate. Figure 5.20 Leaf anatomy in a C4 plant.

WebThe mechanism of photosynthesis in C4 plants was elucidated in the 1960 s by Hatch and Slack in Australia. C4 plants are so-called because the first product of CO2 fixation is a C4 organic acid, oxaloacetate, formed by the carboxylation of phosphoenolpyruvate (PEP) by PEP carboxylase.
